Researchers from Tianjin University and South China University of Technology have pioneered a revolutionary organic lithium-ion battery, addressing critical safety and performance challenges in energy storage. Published today in Nature, the innovation promises to reshape industries reliant on flexible and resilient power solutions.
Led by Professor Xu Yunhua, the team developed a polymer-based organic cathode material called poly(benzodifurandione) (PBFDO), achieving an energy density of over 250 Wh/kg – surpassing conventional lithium iron phosphate batteries. The design eliminates dependence on scarce metals like cobalt and nickel while offering unprecedented operational flexibility.
Key advancements include stable performance across extreme temperatures (-70°C to 80°C) and successful safety tests under bending, compression, and puncture scenarios. “This technology breaks free from traditional limitations,” Xu explained, noting its potential to power next-generation wearable devices and adaptable energy storage systems.
With pilot production plans underway, the breakthrough could accelerate China’s transition toward sustainable battery solutions while meeting global demand for safer, eco-friendly power sources.
